T 0 all whom it may concern lle it known that l, SHERMAN W. (lanY, acitizen of the United States. redding,T at Hamilton. in' the county of\Vcnt\\'ortl| and the Province of Ontario, Dominion ot' Canada. haveinvented certain 'new and useful Improi'enrents` in Balunced-xlc(lultirators. ol' which the following: is a full. clear. and exactspecification.

This invention relates to tillage implements and is shown illustrated inconnection with a type of straddle row cultivator shown in a copendingapplication ot' (lhai'les Sharp #.3Il,l)-l5, filed October 4. lilla.

The ,general arrangement ot' the cultivatin-` to which the invention isyshown applied, comprises an arched wheel axle havin;r tor Wardlyextending' arms swiveled thereto. the arms carrying* the. supportinglwheels near the swiveled connection with the axle and at their forwardends being' connected with a cross member to which the gang' frames are,attached. lln swiveling the wheels hy means of foot levers for thepurpose ot r-teerirgr the deviceq the cross men her slides laterallyYwith respect to a rigidi longue carryingr 'tramo upon which the crossmember hears. and in this lateral motion ca 1ries with it the gang ortool carrying frames. `his results in a multiplied lateral motion o thetool carrying: trames' with reference' to the lateral motion of thecultivator as a Whole. occurs in a numher of differently designed cultivvators now commonly in use.

A merit. of the above-mentioned type of cultivator is that hy rockinefthe 'forwardlyT extending arms. cross connection and wheels as a unitaround the Vertical portions of the arched axle. the vehicle is steeredand the gangs are shifted toward the changed direction of travel Withoutchanging their angie? lar settingV with respect to the normal line ofdraft and hilt a simple mechanism is re# quired.

The purpose of the present invention is to provide in the tvpe ofmachine described for properly maintaining` its halanee as the toolcarrying frames are raised and lowered without necessitating materialadditions thereto or in any wav making; less satisfac- K torv the normalaction of the machine. Sneh counterlialancine' is frequentlvaccomplished hv shittingr the supporting Wheels lonfritndi nallv withrespect to the tool gana frames, and results in certain disadvantages incon- L-shaned struction and action. In the present caseeininterbalaneing is effected hy causing the tongue traine` seat andother parts supported therehy to more longitudinally as a unit withrespect to the remainder of the machine, in correspondence with thevertical motion of thc gang frames. The tendency ot' the machine to tiltforwardly or rearwardly when the tool earning trames are raised andlowered is thus counteracted without a`ecting the action of themechanism for steering' and lateral shiftingl ot' the gang.

Figure 1 is a plan View ot' the cultivator constructed in accordancewith this invention:

Fig. L is a side elevation with one Wheel removed and `showing the toolframes in lowered position: and

Fig. 3 is another View like Fig. 2 hut with the gane* trames in raisedposition. and with the seat and tongue moved forwardly with respect tothe remainder of the machine, as occurs upon the raising of the gangframes.

Cultivators are usually so arranged that while at work in cutting atsome normal or predetermined depth. the reaction of the soil against thesoil working tools will be suhstantially in the line of draft. andtherefore such devices have the tendencyY to rotate around the axis ofthe simpel-ting wheels only when the tool carrying frames are raised orlowered with resnect to their normal working' position. This may resultin an objectionable vertical motion of the tongue and annoyance to thedraft animals, particularly when the tools are raised clear 'pt thearound noon turningy at the end of a frow. Such action nreferftbly iscollateracted in the nresent design hv cansinor a relative longitudinalmotion between main supporting;r structure of the machine including' lthe supportino wheels and fang frames, and the torene and seat support.during the raisine and loweringr of the gangs.

Pl-re' eultivator to which the present improvements are applied is shownin the drawings as havin,er snnportine wheels 1 journaled on lateralextensions 2 of upwardly and forwf-rfllv efztendin'r arms 3. Tlrese armsare bolted to hrackets 4 rwtfit'ihlv mounted en Yerticallv disposedpartera of axles 6V rThe unner inwarfllv ex'- tendng parts 7 of theaxles 6 are. as asu-vl in this type of machine, adjrrstably Securedwithin sleeves 8 by means of collars 9, which are partly encircled bysleeve.

The axles 6 are in gather, while the end portions of the this mannertied tosleeve S is tree to rotate a limited extent around the portions Tof the axles. The arms 3 are tied together at their forward ends by atool beam sup orting har l0 and a transverse I-beam 11. ach arm 3 has avert-ical end portion 12 eatending into the socket of a bracket member13, connecting the har 10 and beam 11. The tool frames 14 carry sleeves15 at the"Y forward upper ends, encircling the bars 1U, and are by meansof links 16 and lever 17 secured to the bar to move therewith during theswiveling motion of arms 3 and brackets 4 on the portions of 5 of axles6. The arms 3, being parallel and Amovingr in an are around the parts 5,maintain the beam sup-A porting bar 10 parallel with sleeves 8 duringthe swiveling motion, and accordingly the tool frames 14 are maintainedparallel with the normal line of draft when the vehicle is stee dtoright and left far enough to cause t e soil working tools to avoidcutting irregular plants of a row. i

The mea-ns for etfectin;r the steering acv tion consists of foot levers18 pivoted to seat trame 19 at QQ, and at their Jforward upper endsbeing attached to chains 21 which pass around lixed pulleys 2Q and thenextend inwardly where they are attached to u casting 23 secured to thetool beam supporting bar 10. By this means. when the lower end of one ofthe foot levers 18 is pushed forwardly, lthe member 10 is shifted eitherto the right or to the let't, depending,r which foot lever is forcedforwardly, thus Swingingr the arms 3, brackets Ll and wheels 1 aroundtheir pivotal support 5.

In order to adjust the gang trames 14 toward or away from each other soas to operate closer or farther away from a row ot plants between thegangs, the lever '17, to which the links 16 are attached at oppositeends may be rotated around its central pivot on castingr Rotation ot"lever 1T is effected hy an adjustable and lockable handle Q4.

tongllu` 25 from which depends the usual swingrletrcos4 und hangers 50.is pivoted hy bolt 2li to a draft frame QT. forming;r an cve tension ot'scat trame 19, and is vertically adjustable. for the usual purposeottool trouw leveling;v at ditferent cutting depths` an iud the holt 2Gby means of a lever 28 which is pivolcd to a bracket 29 secured to therear end of tongue 25 und having: a quadrant 30. to which the lci'er 2Smay be lockt-d in its tliilrieiit adjusted positions. The lover S isconnected by a link 31 to a tic liar 3Q of trame QT.

The structure so tar mentioned in thereterence numbered part ot' the,description is substantially the same as that shown iu thebefore-mcntioned copending application. The present improvements relate.partn'ir larly to the unit formed by seat sulpport lil frame 27, tongueQ5. and the tool irar raising nuchanisin which is arranged iimpartlongitudinal motion to saif unit dm ing the raising and lowering of theloo. frames.

The tollowiing description relates to the construction and. operation ofthe new fea tures:

The scat support d and the draft traum 27 are secured top-ether byvolte-shaped cast ings 33 and comici-ting iinks spectively riveted tothe frames l!) and il by the rivets 35, and ljt' and 2U. The cast ingsare properl Y formed to provule bean mgsfor the pulleys 22 and formabutments for the I'beams which normally ride on rollers 3T journaled inthe members The gangs are raised and the unit formed by seat frame 19,trame 27 and tongue 25 is shifted forwardly at the same time by means ofa lever 38 pivoted to a quadrant 39, in turn attached to frame 27.Forward of its pivot 40 the lever 38. is pivotally connected with a link41 which extends rearwardly and at its rear end is pivotally connected.with fan arm l2 rigid with sleeve S. The frame 27 at its rear end isalso pivoted to arms 43 rigid with sleeve 8. Accordingly, when lever 38is rocked upwardly from a position in which it is shown in Fig. 2 tothat shown in Fig. 3, the sleeve Q is rotated to the right, causingforward movement of the frame, seat support 19 and tongue 25 attachedthereto with res ect to the re -mainder of the machine. Jink 41 servesas a downwardly. moving fulcrum Jfor lever 38 so that a horiatmtalmotion only will be imparted to the seat support and tongue The sleeve@carries quadrants 44 whiii are normally engaged by locking dogs 5 onindividual gang adjusting bell crank levers 46. These levers areaccordingly caused to rock to the right upon the righthand rotation ot'sleeve 8. as above described. YThe lower ends of levers 46 are connectedby lifting rods 47 with the gang frames 14.

lith the construction described, the unit Jformed by seat support 19,frame 27 and tongue 25is shttable forwardly and rearwardly by'means oflever 38 which simultaneously acts as a gang raising and lowering:lever. The weight of the operator and the tongue is thus shiftedforwardly or rearf wardly with respect to the pivotal axis 2 according'to the extent the shovel gangs are raised or the depths to which thetools ltereon are caused to penetrate the soil. L

Lifting of the gang frames and forward motion ot the seat and tongueunit is assisted by a counterbalancing spring iS ez;-V

Iil which are ro y Larsson? ,tending between an erm 49 on sleeve 8 andthe yoke-sl1a-ped bracket member 33.
